Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a panel structure of a plasma display panel, that is, a PDP, and a driving method thereof.

[0002]

2. Description of the Related Art The structure of a conventional discharge display device, that is, a so-called plasma display panel (PDP) is roughly divided into XY
There are a DC PDP having a structure in which the metal surfaces of a plurality of electrode groups constituting a matrix are exposed to a discharge space, and an AC PDP having a structure in which the surface of an XY matrix electrode group is covered with an insulating layer. One of the XY electrodes is an AC type and the other is a DC type half A.
P called C type PDP or hybrid type PDP
There is also a DP.

A PDP having a structure shown in FIG. 10 as a typical example of a hybrid PDP is a self-scanning memory PDP.
Called. This has a DC-type XY matrix on the back side of the panel, a perforated metal plate called a priming plate on the front side, and an appropriate gap between the priming plate and the spacer on the front side with an appropriate gap.
There is a C-type display electrode. This PDP has a scanning discharge section having a self-scanning function composed of a DC type XY matrix, and sequentially moves the scanning discharge for each cathode while synchronizing with the scanning discharge according to an image signal and displaying a display signal to a scanning anode. A low voltage pulse is applied to block the discharge for a short period of time in response to the negative voltage of positive and negative space charges generated by the scanning discharge. Form a negative wall charge on the layer. Thereafter, an AC memory discharge is performed between the display electrode and the priming plate. In this case, since the scan discharge once excites all the pixels for each scanning line regardless of the signal, the scan discharge has excellent rising characteristics when a signal is applied and a high writing speed. Note that the image signal is applied to the anode on the scanning side as a scanning discharge inhibiting pulse, and the display electrode is a so-called solid electrode having no XY address function.

As a DC type PDP having a memory function, a method called a pulse memory method is used, which utilizes the fact that a discharge cell once discharged is easily re-discharged due to the presence of metastable atoms and charged particles existing in space. DC type PDPs as shown in FIG. 10 have been studied for a long time. In this method, the electrode configuration of the panel is a DC type and is formed by a simpler process than the AC type. The self-scanning memory type PD
One of the features is that the auxiliary scanning discharge can be used by making use of the DC-type feature similarly to P, so that the response characteristics are excellent and the gradation display can be performed smoothly.

A typical type of AC type PDP in which the surface of a display electrode is covered with a dielectric layer has a structure called a three-electrode surface discharge type, and a writing electrode, which is one of electrodes constituting an XY matrix, has an insulating layer. DC type without XY
The other electrode of the matrix is an AC electrode covered with an insulating layer. A paired with the AC type write electrode, A
An electrode called a sustain electrode common to all pixels performing C-type memory discharge is also an AC type covered with an insulating layer. In this case, since the memory discharge is performed at the AC electrode, the life is considered to be long.

[0006]

In general, in the case of a color PDP used as a PDP, particularly as a television or a personal computer monitor, it is important to consider how to increase the response speed of discharge and the structural positional relationship between the phosphor and the electrode. The point is what to do, and many ideas have been devised. PDP
In order to colorize the phosphor, a method of applying a phosphor near the discharge cell and exciting it with ultraviolet rays from the discharge is used, but it does not hinder the operation of the discharge electrode, and the phosphor deteriorates due to ion bombardment. It is important to be creative. In addition, gradation display of each color of RGB is indispensable for colorization, and for that purpose, response speed of discharge is important. In order to increase the response speed of the discharge, a so-called priming method in which a constant priming is always performed from a part unrelated to the display, that is, a supply of charged particles such as ions and electrons, or metastable atoms, or
There is a so-called trigger method in which charged particles are accumulated in advance on or near an electrode as wall charges, and a small preliminary discharge is generated prior to discharge.

In the above-described existing technology, first, in the self-scanning memory type PDP, the scanning circuit is used as a priming source by using a scanning discharge by a DC-type XY matrix electrode on the back side, thereby simplifying the scanning circuit and increasing the speed of the panel. However, in practical use, it has been difficult to achieve a single color of only the gas discharge emission color. Because, in this structure, the upper surface of the priming plate facing the display electrode becomes the electrode surface of the display discharge, and when the display discharge, which is an AC discharge, is performed, both surfaces are subjected to ion bombardment. Because you can't.

In the above-mentioned conventional technique, since the priming plate is not covered with the dielectric layer, its metal surface is exposed on the scanning side, and depending on its potential, no-load discharge occurs between the priming plate and the cathode. In addition, the selection of the operating voltage is limited, and stable operation is difficult.

In the pulse memory type PDP, since the display electrode is of a DC type, the electrode itself has no memory function, and a sustain pulse is applied immediately after the address discharge before the priming of the discharge space disappears. There is a limitation on the driving method because it is necessary to keep applying the voltage in the middle. The biggest drawback of this method is the countermeasure for overcurrent, which is a stochastic arc-like discharge. Therefore, as shown in FIG. 11, it is necessary to insert an independent load resistor for each cell, but this is a problem in the process.

In an AC type PDP, since the XY electrodes are subjected to ion bombardment in a structure called a basic two-electrode type, there is a restriction on a place where a phosphor is applied. To solve this, a so-called three-electrode type ACPDP has been devised. In this case, the problem of the ion bombardment was reduced by performing the sustain discharge on the same surface to secure the phosphor-coated surface on the opposite surface.However, there is no priming source, so there is a limitation on the response speed, There were difficulties in increasing the number of gradations and increasing the resolution.

[0011]

As described above, in order to improve the response speed, which is a problem of the prior art PDP, a priming supply source is provided on the rear substrate side, and charged particles supplied therefrom are displayed on the display side. It accumulates as wall charges corresponding to the image on the AC structure electrode, and performs a continuous memory display discharge using the wall charges. Further, in order to secure a place for forming a phosphor screen required for colorization by the PDP having the above structure, pulse memory driving is performed as at least one of the discharge electrodes of the AC type to manufacture a conventional DC type pulse memory PDP. This eliminates the formation of a load resistance for each element, which has made it difficult to avoid destruction due to undesired current concentration that occurs statistically.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to FIG. 1 showing one embodiment of the invention described in claim 1 and FIG. 2 which is a sectional view thereof. First, a striped anode 8 is formed on the back glass 9 by a method such as screen printing. The anode 8 is formed by firing a conductive paste such as nickel, aluminum, or silver at about 550 to 600 ° C. The striped partition walls 7 are also formed on the rear glass 9 so as to partition a space in parallel with the anodes 8 and for each anode. This can also be easily formed by firing a low-melting glass paste in multiple layers by screen printing and firing.

The cathode 6 extends in a direction orthogonal to the anode 8 and the stripe-shaped partition 7 and is formed on the inner wall surface of each small hole 12 by a method such as screen printing on the insulating layer 11 covering the perforated metal plate 10. It is formed as if a part is exposed. Alternatively, the cathode 6 may be a strip-shaped lead frame formed by etching a metal wire or a metal plate, and this may be stretched between the striped partition 7 and the perforated metal plate 10. In the case of printing, the cathode 6 is made of a conductive paste such as nickel, aluminum or silver. When a metal plate or a metal wire is used, a material called iron-nickel alloy, for example, a 426 alloy, whose thermal expansion coefficient is similar to that of glass is suitable as a material. Further, after a glass material is attached to the dielectric layer 11 by an electrodeposition method or a screen printing method, the dielectric layer 11 is heated to about 500 ° C. to 600 ° C.
And formed by firing.

The grid-like partition walls 4 are formed on the perforated metal plate 10 so as to surround the small holes 12. The partition can be formed by screen printing or the like, but can be easily formed by excavation of a glass layer by a sand blast method or a lift-off method using a photosensitive material. After forming the grid-like partition walls 4, the phosphor 5 is also applied to the wall surface of each grid and the upper surface of the perforated metal plate by a method such as screen printing.

On the other hand, display electrodes 2 in the form of stripes are formed on the front glass 1. This may be formed by a method such as screen printing of a conductive paste such as nickel, aluminum or silver.However, a transparent electrode such as indium tin oxide or a chromium copper vapor-deposited film is etched in order to prevent the front emission of light emission as much as possible. An electrode formed in a thin stripe shape is used. The dielectric layer 3 covering this and a protective film made of magnesium oxide or the like, which is not shown in the drawings but protects the surface thereof, are formed by screen printing or vacuum evaporation.

The members formed as described above are laminated as shown in FIG. 2 which is a sectional view, and then the periphery of the front glass 1 and the back glass 9 is vacuum-sealed with frit glass or the like, and helium is contained therein. A gas suitable for electric discharge, such as xenon, is sealed to form a PDP. The operation of the PDP having this structure is described in another claim 5 of the present invention, and a detailed description will be given later.

[0017]

In FIG. 3, the perforated metal plate 13 integrated with a lattice-shaped partition wall is the same as that in claim 1.
After the lattice-shaped partition wall 4 and the perforated metal plate 10 in the embodiment of the invention described in 1) are integrally formed from a single metal plate, the entire surface is covered with a dielectric layer 11. The formation of the grid-like partition walls 4 and the small holes 12 is, for example, from 0.15 mm to 0.1 mm.
A metal plate having a thickness of about 20 mm is formed by etching from both sides. The method of coating the dielectric layer 11 is exactly the same as described above, and the other members are formed and assembled in the same manner as the above-described method. The operation of the PDP having this structure is described in another claim 6 of the present invention, and a detailed description will be given later.

[0018]

Third Embodiment An exploded perspective view of the third embodiment of the present invention is substantially the same as FIG. 1 for explaining the first and second embodiments of the present invention. Will be omitted, and a description will be given with reference to FIG. In the present invention, the structure is substantially the same as that of the first and second aspects, but there is no dielectric layer 3 covering the display electrode 2, and the display electrode 2
Is a so-called DC type electrode. In this case, the display electrode 2 has its metal surface exposed in the discharge space, and a conductive paste such as nickel, aluminum or silver may be formed by screen printing or the like as described above, but in order to improve the characteristics. The surface may be coated with another material such as lanthanum hexaboride. The operation of the PDP having this structure is described in another claim 7 of the present invention, and a detailed description will be given later.

[0019]

Embodiments 4, 5, 6 and 7 of the present invention.
The inventions described in 6 and 7 all relate to a method of driving a PDP having the structure of the above-described invention. Here, the description of the parts common to the embodiments of the invention described in the claims will be described first. Then, the description of the different operation parts for each embodiment will be separately added. The part common to each claim is that the scanning discharge operation of the XY matrix and the charged particles generated therefrom are used as wall charges as the display electrode 2 of the display part.
On the dielectric layer 3 or on the perforated electrode plate 13 integrated with the lattice partition. This will be described based on the fourth embodiment.

A fourth aspect of the present invention relates to a method of driving a PDP having the structure of the first aspect. One of the embodiments of the present invention is an explanatory diagram of a simplified circuit connection shown in FIG. This will be described with reference to a pulse timing chart applied to each electrode in FIG. First, the anodes 8 are commonly connected via a load resistor R, and the switching circuit turns on and off the voltage Va-on (for example, +100 V) and the light-off voltage Va.
−off (for example, 0 V) is applied in a pulse shape.
The cathode 6 has a lighting voltage V k-on (for example, −150).
v) and the turn-off voltage V k-off (for example, 0 V) are sequentially applied to each cathode. That is, the scanning discharge is performed in order from the cathode at the top of the screen, and all intersections, that is, all cells are sequentially turned on. A blanking period is provided in the latter half of the scanning discharge of each cathode.

In the structure according to the first aspect, a perforated metal plate 10 is provided.
No special voltage is applied here because is simply used as a substrate. Then, a display voltage V d-on corresponding to the image signal is applied to the display anode 2 in synchronization with the blanking period.
(For example, +100 V), and when there is no signal, a non-display voltage Vd-off (for example, 0 V) is applied. First, when a scanning discharge is generated in a specific cathode, the discharge space of the scanning unit is ionized to be in a plasma state. Therefore, when a blanking pulse, that is, a turn-off voltage Va-off is applied to the anode side, the scanning discharge is temporarily stopped. At this time, if the display electrode 2 is at the non-display voltage Vd-off (for example, 0 V), the movement of the charged particles does not occur. However, if the display voltage Vd-on (for example, +100 V) is applied, it is generated by the scanning discharge. Negative charges, ie, electrons, of the charged particles are
Side and charges the surface of the dielectric layer 3 to form negative wall charges. In FIG. 5, the display voltage pulse is applied in synchronization with the blanking period. However, during the time when the scanning discharge between the cathode 6 and the anode 8 is performed, no charged particles come to the display electrode 2 side. There is no need to be strict.

In this manner, a distribution of negative wall charges corresponding to an image signal is formed on the dielectric layer 3 covering the display electrode 2, and the next memory display is made utilizing this distribution of wall charges. It shifts to the discharge period. In the memory display discharge period after this, there are basically two different types of memory display methods. That is, positive and negative wall charges are alternately accumulated on the insulating layer during the memory period to sustain the discharge, and the above-described wall charges formed during the address period are used at the beginning of the memory discharge, but thereafter, regardless of the wall charges. This is a so-called pulse memory system using priming remaining in the space. These two types of driving methods have already been filed by the same inventor (Japanese Patent Application No. 8-285829), and the basic operation is the same. However, even if the basic operation is the same,
Since the driving method varies depending on the form of the electrodes and the mutual relationship between the scanning electrode and the display electrode, the present invention is described as a new invention relating to the driving method as claims 4, 5, 6 and 7.

[0023]

[Fourth Embodiment] In the driving method according to the fourth aspect of the present invention, the negative wall charges accumulated on the surface of the dielectric layer 3 as shown in the pulse timing chart applied to each electrode in FIG. In the memory display period after the end of the address period, first, a low voltage V sus (for example, −200 V) sufficient for discharge is applied to all the display electrodes 2 at once. At this time, the anode 8 and the cathode 6 of the scanning unit are kept at the off potential, for example, 0 V for both electrodes. Then, a cell in which a negative wall charge exists in the dielectric layer 3 of the display electrode 2 is applied to the V.sub.
Since a lower voltage superimposed on sus is applied, a new discharge is generated only in the cell where the negative wall charge exists. This discharge causes charges of the opposite polarity, that is, positive ions, to accumulate on the surface of the dielectric layer 3.

Therefore, if a negative pulse is applied after shifting the phase between the display electrode 2 and the cathode and / or anode on the XY matrix side, the memory display discharge can be continued. In this case, for example, a sustained discharge is also possible by applying an AC pulse of both positive and negative polarities to only the display electrode 2 and keeping the anode 8 and the cathode 6 constant at 0 V, for example. In order to stop the memory display discharge, a narrow pulse erasing method generally used in a normal AC type PDP is effective.
The discharge may be stopped by applying a thin pulse of ec or less to cancel the wall charges and not to accumulate wall charges of the opposite polarity.

[0025]

Fifth Embodiment In the driving method according to the fifth aspect of the present invention, negative wall charges accumulated on the surface of the dielectric layer 3, as described with reference to a pulse timing diagram applied to each electrode in FIG. In the memory display period after the end of the address period, a low voltage Vsus (for example, -200 V) sufficient for discharge is applied to all the display electrodes 2 at once for a short time (for example, 1 μsec or less). At this time, the anode 8 and the cathode 6 of the scanning unit are kept at the off potential, for example, 0 V for both electrodes. Then, in the cell where the negative wall charges exist in the dielectric layer 3 of the display electrode 2, a voltage superimposed on the previously applied V sus is applied, so that a new discharge occurs here.

However, since this discharge is performed with a very narrow pulse-like voltage, charges of the opposite polarity, that is, positive charges, are accumulated on the surface of the dielectric layer 3 by the same principle as that of the above-described narrow pulse erasing method. Never. However, the display space is in a state where a large number of charged particles and metastable atoms are supplied abundantly by the discharge, and the display space is in a state where the discharge is easier than in the other cells that did not discharge. Therefore, as shown in FIG. 6, by continuously applying a narrow pulse to the display anode 2, discharge can be continued only in the display cell without forming wall charges. That is, even if an AC electrode is used, pulse memory driving similar to that of the conventional DC electrode can be performed.

[0027]

Sixth Embodiment A driving method according to a sixth aspect of the present invention relates to a driving method of a PDP having a structure having a perforated metal plate 13 integrated with a grid-like partition shown in a sectional view of FIG. . The method of accumulating negative charges on the surface of the dielectric layer 3 according to the image signal during the address period as described above is the same as the method described above, that is, the method shown in FIG. The perforated metal plate 13 is used as one electrode of a memory display discharge, and positive charges are accumulated on the surface of the dielectric layer 11 and the phosphor layer 5 covering the perforated perforated metal plate 13 in the address period during the address period. The method is shown in FIG.
This will be described with reference to a pulse timing diagram applied to each electrode shown in FIG.

As shown in FIG. 7, during the address period, the potential of the perforated metal plate 13 integrated with the lattice-shaped partition wall is slightly higher (for example, -100 V) than the lighting potential V k-on (for example, -150 V) of the cathode 6. Degree). This is because erroneous discharge does not occur between the anode 8 and the perforated metal plate 13 integrated with the lattice-shaped partition wall regardless of the selection of the cathode. In this state, when a display voltage V d-on (for example, +100 V) is applied to the display electrode 2 in the same manner as described above, negative charges, that is, electrons, of the charged particles generated by the scanning discharge move to the display electrode side, and the dielectric particles move to the display electrode side. The surface of the layer 3 is charged to form negative wall charges, and at the same time, ions, that is, positive charges are accumulated on the surfaces of the dielectric layer 11 and the phosphor 5. In this manner, in the memory display period after the end of the address period, the potential of the perforated metal plate 13 integrated with the lattice partition is set to, for example, 0 V, and a low voltage Vsus (e.g.
When v) is applied for a short time (for example, 1 μsec or less), in the cell in which the wall charges are accumulated, the wall voltage due to each wall charge is superimposed, and the actual applied voltage becomes higher. Discharge occurs between the display electrode 13 and the display electrode 2. Thereafter, pulse memory driving can be performed between both AC electrodes by continuously applying narrow pulses.

[0029]

[Embodiment 7] A driving method according to a seventh aspect of the present invention includes a perforated metal plate 13 integrated with a grid-like partition shown in a sectional view of FIG. 2 relating to a driving method of a PDP having the number 2. This method will be described with reference to a pulse timing chart applied to each electrode in FIG. 7, which is an explanatory diagram of Embodiment 6. In this case, since the display electrode 2 does not have a dielectric layer, the accumulation of wall charges is only positive charges accumulated on the perforated metal plate 13 integrated with the lattice-shaped partition wall.
As in the above-described seventh embodiment, in the memory display period after the end of the address period, first, a low voltage Vsus (for example, -200 V) sufficient for discharge is applied to all the display electrodes 2 at once for a short time (for example, 1 μsec or less). In the cell in which the wall charges are stored, the wall voltage due to the respective wall charges is superimposed and the actual applied voltage is increased, so that a discharge occurs between the grid-shaped partition wall-integrated perforated metal plate 13 and the display electrode 2, Further, by continuously applying narrow pulses, pulse memory driving similar to that of the seventh embodiment can be performed.

[0030]

Eighth Embodiment The details of the present invention will be described with reference to FIG. 8 showing one embodiment of the invention described in claim 8 and FIG. 9 which is a sectional view thereof. First, a striped cathode 6 is formed on the back glass 9 side by a method such as screen printing. The cathode 6 is formed by firing a conductive paste of nickel, aluminum, silver, or the like at about 550 to 600 ° C. The striped partition 7 and the grid-shaped partition 4 are arranged on a plane so as to share a part of the partition with each other. The scanning discharge part partitioned by the stripe-shaped partition 7 and the display discharge part partitioned by the lattice-shaped partition 4 are electrically connected to each other by a slight gap on the front side so that charged particles and metastable atoms can easily move. doing. The partition walls can be easily formed by multilayer printing of low melting point glass paste by screen printing or the like and firing. The phosphor is formed on the inner wall surface of the grid-like partition 4 by screen printing, sandblasting, or photographic method.

Next, on the front glass side, an anode 8 constituting an auxiliary discharge portion is formed so as to extend in parallel with the stripe-shaped partition wall 7. A conductive paste such as nickel, aluminum, or silver is used for forming the anode 8. The display electrode 2 is a grid-like partition 4
Across the section and orthogonal to the cathode. After the display electrode 2 is formed, a dielectric layer 3 is formed so as to cover the display electrode 2. The dielectric layer 3 is formed by screen-printing a low-melting glass paste, and its surface is further covered with magnesium oxide as a discharge protection layer. The method of driving the PDP having this structure is the same as the driving method of the fourth and fifth aspects described above, and the description thereof is omitted here.

[0032]

First, the effect common to the PDPs having the structures according to the first, second and third aspects of the present invention is that the response speed, which is a major problem of the conventional AC type PDP, is increased on the rear side. The problem is solved by the auxiliary discharge effect of the arranged DC electrodes. In addition, as a member that separates the scanning unit on the back side and the display unit on the front side, a metal plate molded and covered with a dielectric layer can be used to achieve the object easily, and the partition can be formed at the same time, greatly reducing the size. Simple process simplification is achieved. According to the driving method according to the fourth, fifth, sixth, and seventh aspects of the present invention, the P
As a method of driving the DP, a stable operation can be obtained by taking over the auxiliary discharge and the memory discharge via the wall charge, and further, by taking over the pulse memory drive as in claims 5, 6, and 7, the fluorescent light is generated in the panel structure. It secures a place for applying the body and contributes to the improvement of luminance and luminous efficiency. Further, in the PDP having the structure according to the invention of claim 8,
By making the structure of the first, second and third aspects a planar structure, productivity can be further improved.

Charge is again on the dielectric layer It continuously excites the discharge by the pulse with the width shorter than the accumulation time, and continues by the so-called pulse memory discharge that uses the discharge voltage drop phenomenon due to the priming residual effect of the space instead of the voltage difference due to the charge with the non-selective electrode. A method for driving a PDP, wherein a typical memory display discharge is maintained. 7. A method of driving a PDP having a structure according to claim 3, wherein during the address period, the display electrode is driven high according to an image signal in synchronization with the blanking period of the scan discharge. By applying a voltage, for example, a voltage pulse having a potential higher than the discharge sustaining potential of the scan discharge, the scan discharge which is a DC discharge is moved to the display side, that is, to the display electrode and the cathode side of the XY matrix electrode. By applying a voltage lower than the discharge sustaining potential of the scanning discharge to the partition-integrated metal plate, a positive charge corresponding to an image signal is formed on the dielectric layer and the phosphor covering the lattice-shaped partition-integrated metal plate. Then, by continuously applying a narrow negative pulse to the display electrode during the memory discharge display period after the end of the address, display is performed with the lattice-shaped partition wall-integrated metal plate. Discharge by a narrow pulse between the electrodes, that is, discharge is performed, but the discharge by a pulse having a width shorter than the time during which the wall charges of the opposite polarity accumulate on the dielectric layer again is continuously excited, and the non-pulse discharge occurs. A method of driving a PDP, comprising sustaining a continuous memory display discharge by a so-called pulsed memory discharge utilizing a discharge voltage drop phenomenon due to a priming residual effect in a space, instead of a voltage difference due to a charge with a selection electrode. 8. A plurality of DC-type electrodes extending in the horizontal direction, that is, a cathode group having a structure in which the electrode surface is not covered with an insulating layer, is formed on the back glass, and is extended in the vertical direction as the cathode is partitioned. Forming a striped partition on the back glass to form a scanning discharge portion, having a display discharge portion which is partitioned by a grid-shaped partition adjacent to the striped partition and has an inner wall coated with a phosphor, On the front glass, first, an anode group having a DC-type electrode structure is formed in the scanning discharge section so as to form an XY matrix orthogonal to the cathode, and the display discharge section is also orthogonal to the cathode. A PDP structure in which AC electrodes are arranged so as to form an XY matrix, that is, an anode group having a structure in which an electrode surface is covered with an insulating layer.
